The Pros and Cons of a Tankless Air Compressor

Tankless Air Compressor

Do you really need a Compressed Air Tank?

As with any decision in life, there are advantages and disadvantages for everything we do.  When it comes to the decision to buy a tankless air compressor, we need to discuss the good and bad aspects before making a decision.  Actually, when it comes to choosing an air compressor, there is a bit of a paradigm around the air storage tank.

Most air compressors have an air tank!

In fact, the air tank is often an integral part of the design of an air compressor.  The pancake air compressor, hot dog compressor and vertical compressor are all named after the configuration of the air tank.  Furthermore, the structural design of an air compressor is often based around the shape of the air storage tank.  The roll cage and the protective shroud are welded directly to the air tank as part of the integral structure. Even the pressure gauges and connectors are often attached right on the top of the air tank.

 

The advantages of a tankless air compressor

Although it may seem strange at first, it is possible to buy a tankless air compressor.  Many of the smaller 12 volt tire inflators do not have an air storage tank.  There are some ultra quiet air compressors that do not have an air tank. And there are even some heavy duty gas powered air compressors that are designed as tankless air compressors.  There are some good reasons to buy a tankless air compressor.

A tankless air compressor doesn’t need certification

An emerging issue these days is the certification of the compressed air tank.  When it comes to ongoing safety management, the regulatory statutes may require an inspection regime for compressed air vessels.  This can be a hassle to maintain a properly certified compressed air device.  With a tankless air compressor, you never have to worry about having the machine tested and certified.

Tankless air compressor – Lightweight and portable

The biggest advantage of a tankless air compressor is the lighter weight.  Most air storage tanks are made from heavy materials such as cast iron or stainless steel.  Even a small air tank tends to add a lot of weight to an air compressor.  A tankless air compressor can save a lot of weight, and make it much more portable.  Not only is a tankless air compressor more portable, but it is generally smaller also.  Small size is always an advantage when it comes to storing a tankless air compressor when not in use.  But a small tankless air compressor is also much easier to handle, and carry around wherever you need to go.  A small tankless air compressor is much easier to transport in the trunk of the car, or the truck.

Tankless air compressor – instant air flow

Another advantage of a tankless air compressor is that you get instant air delivery.  There is no need to wait around for the air compressor to build up to operating pressure.  With a tankless air compressor, the air is delivered directly from the air outlet, at the desired air pressure.   As soon as you turn on the electric tankless air compressor, it is ready to go!  It is also possible to buy a gas powered air compressor without an air tank.  But it is wise to let these machines come up to operating temperature before starting work.

Disadvantages of a tankless air compressor

Whenever we try to go against the flow, I ask myself, why is everyone going the other way?  In the case of a tankless air compressor, we should ask, why do most air compressors have an air tank?  Without a doubt, the air storage tank serves an important purpose for an air compressor, but do we need one?

An air compressor tank saves power

The key role of an air storage tank on an air compressor is a reservoir for the compressed air.  When the air compressor pump has filled the air tank to the maximum operating pressure, it simply shuts off.  Not only does the automatic shut off save power, but it also saves wear and tear on the machine.  The benefit of having a reservoir of compressed air is that you can draw down on the air supply.  This means that you can continue to use air powered tools and accessories without the air pump running continuously.  When the operating pressure drops below the threshold, the air pump automatically cuts in, and recharges the air supply.  This means that you can buy an air compressor with less horsepower than you really need.  The additional power can be supplied from the air storage tank for the times when you really need it.

An air compressor tank saves maintenance

The Pros and Cons of a Tankless Air Compressor

A Compressed Air Tank regulates the air flow

When it comes to maintaining an air compressor, the amount of running time is important.  The maintenance interval depends on the number of hours that the machine has run for.  The good news is that when the air compressor shuts off automatically, then there is no accumulation of running time.  When the running time is reduced, there is less wear on the air compressor, and less need to do maintenance.

A tankless air compressor runs continuously

The disadvantage of a tankless air compressor is that the air pump has to run continuously.  There is no air supply unless the motor and the air pump are switched on.  This means that the device is drawing energy at all times, and the components are working continuously.  Even if you are not using the compressed air supply.

An air tank acts as a pressure regulator

The benefit of an air storage tank is that the air supply is regulated by the size of the tank.  For example, the fluctuations and irregular flow of air from the air pump are smoothed out by the air tank.  Any pulsations or fluctuations from the air pump are absorbed within the air storage tank.  When the air is discharged from the reservoir, the compressed air is smooth and regulated at the desired operating pressure.  There are no peaks or spikes in the operating air pressure, just a steady air supply at a regular air pressure.

A tankless air compressor may suffer from air fluctuations

The disadvantage of a tankless air compressor is that the air supply is subject to fluctuation in the air flow.  Depending on how fast the motor is running, or whether the air pump is driven by a piston.  There can be noticeable fluctuations in the air pressure when you use a tankless air compressor.
